Product Feature
1. Efficient Thermal Insulation and Sealing
The door body uses high-density insulation materials such as polyurethane foam, combined with double sealing strips around the door frame, effectively blocking cold and hot air convection to reduce cold storage energy consumption. It also prevents external moisture infiltration, avoiding frost and ice buildup inside the storage.
2. Intelligent Sensor Activation
Equipped with radar, geomagnetic, or pull-rope sensors, the door automatically opens and closes based on signals from forklifts or personnel, eliminating the need for manual operation and improving warehousing efficiency. Opening/closing speeds and delayed closing times can be adjusted to suit different scenario requirements.
3. Stable and Durable Drive System
Powered by an industrial-grade reduction motor for smooth, low-noise operation, it adapts to a wide temperature range of **-30°C to +50°C**, meeting the long-term demands of high- and low-temperature cold storage. The motor features overload protection, with automatic rebound upon obstruction to prevent equipment damage or personnel injury.
4. Structural Design Tailored for Cold Chain Operations
The door frame is made of stainless steel or galvanized steel sheets for rust and corrosion resistance, capable of withstanding humid cold storage environments. The door panel surface is smooth and easy to clean, complying with hygiene standards in food, pharmaceutical, and other industries.
5. Multi-Layer Safety Protection
Standard features include anti-collision strips, emergency stop buttons, and audible/visual warning devices. Certain models offer optional infrared anti-pinch sensors for comprehensive protection of personnel and equipment during passage. Manual opening is supported in case of power failure to handle unexpected outages.

FAQS
1. Q: How effective is the insulation of this door? What is the lowest temperature cold storage environment it can handle?
A: The door body is filled with a high-density polyurethane insulation layer and equipped with double sealing strips, achieving a cold air loss rate as low as 5% or below. It adapts to a wide temperature range of -30°C to +50°C, fully meeting the demands of ultra-low-temperature cold storage.
2. Q: Can the door's operating speed be adjusted? Will frequent opening and closing affect its service life?
A: It supports 3-level speed adjustment for opening and closing, suitable for different scenarios involving forklifts or personnel. The drive motor uses industrial-grade wear-resistant gears, with a designed service life of ≥80,000 cycles, ensuring stable operation even under high-frequency use.
3. Q: How do you open the door during a power outage? Is there an emergency opening/closing mechanism?
A: It comes standard with a manual clutch device—simply pull the clutch handle during a power outage to manually push or pull the door. Optionally, a UPS emergency power supply can be added, allowing 1-2 automatic open/close operations even without power.
4. Q: What dimensions need to be reserved before installation? Do you provide on-site measurement services?
A: Reserve space for the door opening dimensions, side installation areas, and top motor mounting position—specific parameters can be found in the product installation manual. We offer free on-site measurement services, with a professional team creating a customized installation plan based on site conditions.
5. Q: Does the door have an anti-pinch function? Will it automatically stop if it encounters an obstacle?
A: Standard features include infrared anti-pinch sensors and obstruction rebound function. If an obstacle is detected during operation, the door immediately stops and reverses. It is also equipped with audible and visual warning devices to enhance passage safety.
